HENRY F. KIEIIJIJNEB, 0F SILYEB LAKE, KANSAS.

To all whom it may concern:

Be it known that I, Harm: Knnnmm, a citizen of the' United Statesresiding at Silver Lake, in the county of Stateof Kansas, haveinvented'certain new and useful'lmprovements in Jetty Construction, ofwhich the following is a specifics tion. I

This invention relates to an improvement in jetty construction, and hasfor one of its objects to; rovideself sinking, angular frames or de'ectors of such construction that hey will,=engage...:the..bed of awater channel to advantage and will not be readily overturned -by-awatercurrent. The invention also'relates to deflectors so constructed thatstrands, when connected to opposed parts thereof will 0 crate to advantae in maintaining the' de ectors substantial y in line. 'Thef'inventiomalso has reference to simplicit' and durability of parts 'so-that'practical, convenient The novel features of the inventiofiare fullydescribedihereinand are pointed out in t e appended claims, and areillustrated in the accompanying drawing, wherein,'

Figure 1- is a perspectivevie'v of one of the angle irons employed. Fig.2 is a perspective view, illustrating a plurality of angular frames'orcurrent deflectors maintained in linein a silt-bearing stream. Fig.

3 is a side or end view of a current deflector, the strands beingomitted, Fig. 4 is a side or end view of a current-deflector providedwith cable "or strands. V

I provi e a plurality of angular frames or current deflectors 5, eachconsisting -of stri s orbars of angle irons, substantially of uni ormlength, as the strips-""6, 7 an 8 *-1,.having one of'its flangesprovided Wi semhled w apertures9,its other flange being-provided with aertures 10, said apertures 9 and 10 "being isposed midway between theends of the strip, each "stripalso being providednear its respectiveends with apertures 11 formed ineach flange.

By use of the strips thus described an angular f ame" may beconveniently asifch, when placed in swiftly moving water I overturned,since it will provide three prongs, as will be seen, which will engagethe bed) of the channel, each flange of an angle iron being inengagement witha flange Specification of Letters Patent.

of an adjacent angle-iron strip, rivets or equivalent keepers 12 beingemployed and Patented Oct. 8,'1918.-

traversin the apertures 9 and -10, and thereby pro'vi mg a connectionfor the strips midway'between their ends, each end of each stri beingconnected with an end of each of t e remaining strips by means ofstrands 13, whereby stresses directed to the outwardly pro eCting prongsor end portions of the strips will be adequately resisted.

Means are provided for maintaining the angular frames thus provided inconnected relation when placed in a stream or water channel, as thestrand 14, which is secured to each frame at its middle, and 'which'issecured to an anchor-post 15 upon the bank,

as shown in Fig. 2.

Also means are provided for preventing inversionof the deflectors orframes, consisting of the strands 16 and 17 these being secured,respectively, to the two adjacent upper ends of two of flector, thestrand 16 being secured to an anchor-postl8 on said bank and the strand17 being secured to the anchor-post 19 on the bank. It will beunderstood that if the posts 18 and '19 are spaced apart transversely ofthe line of the deflectors, as shown in the drawing, this arrangementwill tend t'he-strips of each deto prevent inversion of the frames, andon account of their form and Wei ht, .the

frames will so engagethe bottom where the water moves very swiftp'andinsuch instances additional anchorage (not shown) may be provided.

The construction thus described is'of advantage in the formation ofall-uvia de posits in silt bearing streams. Since-all of" the partsareconstructed of iron, the frames will readily sink, and on account ofthe peculiar form the force of moving "water, the outwardly divergentprongs normally engaging the bed of a stream regardless of the positionof the frames. i l

In operation, several of the frames may be connected and, secured "tothe bank 20 of a stream2l, the straight or curved lineof the connectedframes water carrying silt or sand and moving the direction indicated bythe arrow shown in Fig. 2, will causeal 5 being transverse tothe-liowing water and disposed at any desired angle with referencethereto 5 and 110 o a channel that they will maintained in linetransversely thereof except in instances for the frames they will resistuvial deposits 22 i below or down stream from the deflectors or frames5, the object, in some instances, being 'toprevent the water fromcutting away the land or banks of a stream; also to change the directionof water currents, and also to cause accumulation of land at a waterfront. In the for1nation-of jetties in tide waters the frames, whenconnected, are disposed transverse to the flow of the tides, the resultbeing that sand bars will form at each side of the line of the connectedframes, and since the frames are ,durable and on account of their form,they tend to maintain the sand-bars as permanent supports for a roadwayor for piers or wharves.

Having fully described my invention,- what I claim and desire to secureby Letters Patent is,-

1. In jetty construction, a pluralit of current defiectois disposedsubstantial y in line in a water current, each consisting of a pair ofbars of angle iron disposed at right angles and connected midway betweentheir ends and a third bar of angle iron disposed at right angles toeach barof the first pair of bars ofan le iron and connected therewithmidway etween its ends. 2. In jetty. construction, .a plurality of"current deflectors disposed substantially in -line in a water current,each'consist-ing of a trinity of apertured angle-iron strips subothertwo strips, rivets traversing the apertures of theengaging flanges andmet-Quie strands connecting the terniinals of each strip with theterminals of the remainin in strips. 3. In 'jettyconstruction, aplurality of current deflectors each consisting of a pair of strips ofangle iron disposed substantially at right angles and engaging eachother 1nidway between their ends, at-hirdstrip of angle iron disposed atSubstantially right connected therewith-"midway between its ends,strands connecting the ends of each strip 'with the ends. of the otherstrips of angle iron, a cable connected with a strip of. each deflector;a second cable connected with a stri of each deflectorg said cablesbeing secure to a stationarysupport for maintaming the deflectors inline in a Water current. v
